2-Channel 1500W Entertainment-grade Professional Power Amplifier S21500D
Through a single-module integrated design, the power supply and amplification circuit are integrated into one board, combined with a newly designed equal-area, short-path, short-airflow, wave-type molded heat sink structure, it minimizes failures caused by connecting wires between circuits, improves the heat dissipation efficiency of the whole machine, reduces the weight and volume of the product, achieving lower costs for transportation and installation, and realizing a perfect combination of economy and reliability; it uses imported original power tubes with a direct-fit heat sink design, which can more effectively reduce the temperature of the power tubes and improve product stability. The transformer adopts a high dynamic response technology design; it adopts ACL clipping protection and indicator circuit, ensuring the maximum dynamic range of the signal; the output has short-circuit protection, DC protection, infrasound protection, overheat protection, over-temperature protection, surge protection, input overload protection, etc., ensuring product stability and performance.
